The number of moles of solute dissolved per liter of solution is called:
Correct answer: D. Molarity
- A. Normality
- B. Molality
- C. Mole fraction
- D. Molarity
- E. Percentage composition
Explanation
Molarity (M) indicates the number of moles of solute per liter of solution.Molality is a property of a solution and is defined as the number of moles of solute per kilogram of solvent. Mole fraction is defined as the ratio of the number of moles of one component of a solution or other mixture to the total number of moles representing all of the moles in solution. Normality is described as the number of gram or mole equivalents of solute present in one liter of a solution. The percent composition of a component in a compound is the percent of the total mass of the compound that is due to that component.

About Solutions and Colloids
Solutions are described using molarity, molality, normality, mole fraction, percentage concentration and parts per million. Coverage also includes vapour-pressure lowering, boiling-point elevation, freezing-point depression and osmotic pressure, then distinguishes true solutions, colloids and suspensions by particle size, stability, light scattering and settling.
